Pay no attention to what Nathan says Stevie. He probably comes from old world physics and doesn't understand the zero-point physics behind your E2D.

In Nathan's world where transfer of power rules apply, in order to deliver 10 amps at 120V the 12V battery would have to be delivering 100 amps and hence it would be depleted in one hour and not ten.

I think I understand how your zero-point 100:1 gearing can get a 40 watt motor on your windmill to deliver 4000 watts for as long as you like, but how exactly do you manage to get a battery manufactured by someone else to deliver up ten times its rated capacity?

Troy,

A typical automotive bulb for a tail light is around 5 watts, and in a 12V circuit it would draw about half an amp.

If your windmill does not deliver enough power to light up a 5 watt bulb then that explains why it can't charge a battery. Although I suspect the engineers at freetricity are going to tell you that now you have a bad bulb to go along with your bad battery.

I only thought that I did Stevie. Obviously I was wrong. Again! 100 amp hours at 12 volts is 1200 watt hours or 1.2 kilowatt hours. Since your customers are able to get 10 kilowatt hours from a battery you must have put a zero-point physics 10-power multiplier into the inverter. It was silly of me to miss that the first time.

The different batteries and how they work!

1) Car batteries:

These are for short term high amp output to turn your cars engine over to start it. When your engine starts your cars alternator replaces that used current fast because you may just drive 2 miles and shut the car off to get gas and than have to restart it.

If your car has trouble starting the battery will die with moments.

A standard battery charger replicates your cars alternator and charges the battery up quick again (although not as quick as your alternator;

*** Not suited for deep cycle use and a standard battery charger will destroy deep cycle batteries ***

2) Marine or RV batteries:

These are actually a "hybrid", and fall between the starting and deep-cycle batteries with most be much closer to car or starting batteries.

Not really true deep cycle and have a top charging voltage of 15.5 volts.

*** Not suited for E2D’s high voltage that will destroy them. ***

3) Deep cycle:

Deep cycle batteries are designed to be discharged down as much as 80% time after time, and have much thicker plates. The major difference between a true deep cycle battery and others is that the plates are SOLID Lead plates - not sponge. Unfortunately, it is often impossible to tell what you are really buying in some of the discount stores or places that specialize in automotive batteries. The popular golf cart battery is generally a "semi" deep cycle - better than any starting battery, better than most marine, but not as good as a true deep cycle solid Lead plate, such the L-16 or industrial type.

*** Suitable for most applications that have a maximum charge voltage of 15.5 volts ***

*** Not suitable for E2D’s High Voltage output as it will destroy the battery ***

4) AGM Deep cycle:


AGM, or Absorbed Glass Mat Batteries
A newer type of sealed battery uses "Absorbed Glass Mats", or AGM between the plates. This is a very fine fiber Boron-Silicate glass mat. These type of batteries have all the advantages of gelled, but can take much more abuse.  These are also called "starved electrolyte", as the mat is about 95% saturated rather than fully soaked. That also means that they will not leak acid even if broken.

AGM batteries have several advantages over both gelled and flooded, at about the same cost as gelled:

Since all the electrolyte (acid) is contained in the glass mats, they cannot spill, even if broken. This also means that since they are non-hazardous, the shipping costs are lower. In addition, since there is no liquid to freeze and expand, they are practically immune from freezing damage.

Nearly all AGM batteries are "recombinant" - what that means is that the Oxygen and Hydrogen recombine INSIDE the battery. These use gas phase transfer of oxygen to the negative plates to recombine them back into water while charging and prevent the loss of water through electrolysis. The recombining is typically 99+% efficient, so almost no water is lost.

And, since the internal resistance is extremely low, there is almost no heating of the battery even under heavy charge and discharge currents. The Concorde (and most AGM) batteries “HAVE NO” charge or discharge current limits.

Agreed!

A 100 amp hour battery works this way:

1) It can deliver 1 amp for 100 hours or 10 amps for 10 hours. Ergo the "100 amp hour" rating!

2) Our inverter is a 1200 watt inverter at 120 volts.
This is 10 amps!!

3) The inverter draws its 1200 watts (10 amps) from the battery as it is being used.

4) If it does this for one hour it is 1.2 kilowatt hours.

5) If it does it for 10 hours it is 12 kilowatt hours!

We advertise 10 kilowatt hours (instead of 12) each time the battery is fully charged because the inverter does consume some power doing its job.

Except that we are not talking about constant wind not are we talking about a 10 kilowatt hour stream.

What we advertise and sell is a system that is predicated around a fully charged deep cycle 100 amp hour battery.

How long it takes to charge that battery and what that battery can deliver once charged is the essence of our system.

Nothing fuzzy about it!

"Well then, how long would it take to charge the battery."

3 - 5 hours of moderate wind (8 - 12 mph) in most cases!

"Also if you understand batteries, then a 100 amp-hr battery will truly only provide 80 amp-hrs if properly discharged and maintained, in order for long life and for it to be continually recharged."

Not quite true with AGM's but again, that is one of the reasons we advertise 10 kilowatt hours and not 12!

Example:

My golf cart has 6 6 volt batteries making a 36 volt system.

8 hours on the charger lets me play 54 holes of golf or, almost 15 hours of use at a tremendous draw.

14 - 16 an appropriate gage at 12 - 40 volts at no more than 20 amps.

That's what makes it fuzzy....

"When a 120V device draws 10 amps of current it is using 1200 Watts of Power."

Exactly!!

And when it does it for 1 hour it is 1.2 kilowatt hours!

You're getting there!

You lack a thorough understanding of how solid state inverters work!

Yes and that 1200 Watts of power would translate to 100 amps at 12 volts which is the upper limit on your battery for one hours use. If it were 12000 Watts then your battery would have to supply 1000 amps.....

...looks like we got him thinking.....

To add some info about Freetricity and i am not affiliated at all with the alternative energy store .  I am a contractor who sells energy efficient products and was intriqued by Freetricity for personal ise as well as business. I don't know how good the system works but i will say that the company service stinks.  I bought a business teritory almost 2 months ago and still have not recieved two of the three windmills i purchased.  I was told by Carl that a national add campain would be kicked off in the beggining of Nov. I was told i would recieve my products in two weeks,i spent $2000 on a home show and have over 50 people who want the unit but to date have not recieved it.

I would warn anyone interested in this as a business opportunity to look somewhere else.

Hello Troy!

I'm sorry to hear that your situation didn't get resolved to your satisfaction.  We certainly do appreciate you coming back and letting us know how things went. 

Best Wishes,
